To maintain long-term human-robot communication, a robot behavior model based on the behaviors of dogs in human-dog relationships has been proposed. We apply this model to a robot in a monitoring support system designed for home care. This paper presents an improvement to the model, adding behavioral factors to show different characteristics of the behaviors. We conduct experiments to evaluate users' impressions of the robot behaviors when given different characteristics using a simulator. Our findings show that the subjects had the impressions that we expected based on the factors selected.

Pre-execution is a new technique used in conjunction with simultaneous multithreading or multi-core CPUs to reduce memory latency. Executing a slice of a program in a software or hardware thread ahead of the normal execution resolves memory addresses and prefetches data into the caches. By doing so the latency of memory reads is reduced in the main thread. Data intensive applications can benefit from pre-execution even if thread level parallelism is not available because of shared (software) resources. Despite the simplicity of the idea several factors have to be considered when putting this principle into practice. This paper applies and customizes pre-execution to a particular problem of hash table based data transformation and through this example provides a parameterized software preexecution algorithm which can be applied to arbitrary programs and executed on everyday hardware. The most important factor to be considered is to continuously keep an optimal temporal distance between the pre-worker and the main thread, which should be implemented with introducing minimal amount of control and communication dependencies between them. This paper presents a mechanism for attaining this goal.
Software quality is always the target of disagreement between developers and users because of its subjective nature. The problem with software quality is the lack of formal definitions. Furthermore, quality metrics ar...

Fuzzy Flip-Flop based Neural Networks (FNN) constructed from fuzzy D flip-flops are studied as a novel technique to implement multilayer perceptrons. The starting point of this approach is the concept of fuzzy flip-flop (F 3 ), as the extension of the binary counterpart. Fuzzy D flip-flop based neurons are viewed, as sigmoid function generators. Their characteristic equations contain simple fuzzy operations, thus enabling easy implementability. FNNs have an interconnected fuzzy neuron structure composed from a large number of neurons acting in parallel which are capable of learning, and are suitable for function approximation. In this paper we propose the FPGA implementation of Łukasiewicz operations, furthermore of fuzzy D flip-flop neurons based on Łukasiewicz norms.
In the nodes of computer networks the Active Queue Management (AQM) is responsible for managing the messages to be transmitted. Because of the time required for this service the messages delay in the nodes. This delay...
